Abstract Two model aluminium-magnesium alloys, containing 3 and 7.5 wt.% of Mg, were subjected to plastic deformation by means hydrostatic extrusion (HE). degrees imposed two subsequent reductions the diameter. Microstructural analysis tensile tests materials in initial state after performed. For both materials, HE resulted microstructure—formation un-equilibrium grain boundaries partition grai...

Mechanical signals can play a key role in regulating the chondrogenic differentiation of mesenchymal stem cells (MSCs). The objective of this study was to determine if the long-term application of cyclic hydrostatic pressure could be used to improve the functional properties of cartilaginous tissues engineered using bone marrow derived MSCs. MSCs were isolated from the femora of two porcine don...

Elevation of renal interstitial hydrostatic pressure (RIHP) by direct renal interstitial volume expansion increases sodium excretion. This natriuretic response is blunted by the nonspecific inhibition of the cyclooxygenase (COX) enzymes. The present study tested the hypothesis that the natriuretic response to increased RIHP during direct renal interstitial volume expansion is dependent on COX-1...

Extrusion cooking as an attractive process for continuous food production has been extensively developed in recent years. The high temperature–short time extrusion cooking is used in the food industry to produce direct expanded products such as snack foods, breakfast cereals and pet foods (Miller, 1990; Moore, 1994; Rokey, 1994). Extrusion of food material results in starch gelatinization, dena...
